Hello all,
I am new to this community, and am a former member of the armed forces.
Now I am an associate pastor of a church, and we want to do a 4th of July military parade, where our church members active military and veternas will do a flag processional, and stand in attention, while the mayor of the town comes to speak.
Question, should we salute? Some are active, some are veterans. Some veterans will not be uniformed. All of us will be inside a "temple of divine worship."

Since I left the Marines a while ago, I don't remember all of the detailed rules...

can someone help me?
